Study real women so you can understand what makes them fundamentally pass as women, despite that they may have dyke-y hair, act like dudes, be obese as shit, and dress in XXXL potato sacks.
You'll learn how to select and wear your clothes, style your hair, etc with time. There's a lot of little things to learn, many of them purely functional but so common that we associate them with femininity (eg hair accoutrements).
